Fermented bean curd

Fermented tofu is a Chinese condiment consisting of a form of processed, preserved tofu used in East Asian cuisine. The ingredients typically are soybeans, salt, rice wine and sesame oil or vinegar. In mainland China the product is often freshly distributed. In overseas Chinese communities living in Southeast Asia, commercially packaged versions are often sold in jars containing blocks 2- to 4-cm square by 1 to 2 cm thick soaked in brine with select flavorings.
